Gentle giant in spite of looking intimidating (except for being a murderer).
Tessio LSI is my hunch. Possibly another introverted and logical type.
Tom Hagen LII. Mostly comfortable performing the intellectual duties (lawyer stuff) for the family, practically works as an analyst, clarifying possibilities and presenting solutions. Not shown to care much about money, power, personal rank or internal politics (except in so far as it fell under his work or obligations) -- bit of a pushover when it comes to all that. Generally bright, reserved, accommodating, stoic, with an appearance of self-control.
Don Barzini Se EJ. Either one, since we're shown so little about him, but I'd go with EIE since he seems like he'd turn out to be a surface-level narcissist who'd be worried about his status, looking suave and competing with others about minutiae related to his image.
Michael Corleone NT. Perhaps ILI.
Kay Agree with Delta NF.
Fredo Definitely Fe ego.
